Plz help out- Question about passport information in I-765 (STEM OPT) – old passport expired

I’m currently filing my I-765 for the STEM OPT extension and had a quick question about the passport section.

The passport I used to enter the United States (which contains my F-1 visa) has expired. I later renewed my passport and now have a new valid passport.

USCIS instructions say to enter the passport used to travel to the U.S. even if it is expired. However, since I now have a new passport, I’m a bit confused.
